Frequently Asked Questions

Why does Excel open but show a blank gray screen when I double-click a file?

This commonly happens when the Dynamic Data Exchange (DDE) setting is misconfigured, causing Excel to ignore the command to open the specific workbook, or if the default file association is broken in your system registry.

Can I still access my XLSX files if Excel won't open them from File Explorer?

Yes. Even if the file association is broken, you can open the Excel application first, go to File > Open, and browse for your document. It will load normally from within the app.

Will running the Microsoft Office repair tool delete my spreadsheets?

No, running a Quick Repair or Online Repair for Microsoft Office only fixes application files, shortcuts, and registry entries. Your personal workbooks and data will not be modified or deleted.
